The production cost of hydrogen from a mineral acid using zinc is Rs. 12 per mole. How many electrons is worth of one rupee? 

Text Solution

Verified by Experts

Reaction of mineral acid with zinc is given as `Zn+2HCIrarrZnCI_(2)+H_(2)`
The net reaction is `2H^(+)+2e^(-)rarrH_(2)`
1 mole of `H_(2)` = 2 moles of electrons
1 rupee = ?
Number of electrons worth of one rupee `=(1)/(12)xx2xx6.022xx10^(23) = 1.004xx10^(23)`

The observed wavelengths in the line spectrum of hydrogen atom were first expressed in terms of a series by Johann Jakob Balmer, a Swiss teacher. Balmer's empirical formula is (1)/(lambda) = R_(H)[(1)/(2^(2)) - (1)/(n^(2))] = n = 3, 4,5… R_(H) = 109678 cm^(-1) is the Rydberg constant. Niels Bohr derived this expression theoretically in 1913. The formula is a generalised to any on electron atom/ion. How many lines in the spectrum will be observed when electrons returns from 7th shell to 2nd shell ?
